Energy management

Connecting cars and homes

Your car will not just draw energy from your home. When electricity usage is high, your car can help power your home, contributing to the next generation of smart energy management.

Connecting cars and the community

Homes, offices, stores, and factories in your community will link together via cloud technology. Working together, we can create a low-carbon society.

New innovations will enable a more comfortable and ecological lifestyle.

Cars will connect with homes and communities to optimize energy use across entire cities.

Contributing to a more environmental communities

Connecting your car with your town

The Energy Data Management System uses a cloud server to gather energy consumption data from factories, schools, offices, and homes. It then offers advice on how to consume energy in the most efficient way. This system allows facilities with extra capacity to send electricity to buildings requiring more. In the event of a disaster, energy can be precisely allocated for use where it is most needed.

Efficient energy management

Powering your home four days at a time

The Home Energy Management System (HEMS) were developed to share electricity between battery-powered vehicles such as plug-in hybrid vehicles (PHV) and your home. Using HEMS, users can charge vehicles with solar energy during off-peak hours and efficiently power their homes using their vehicles during peak hours, thus drawing less energy from city power grids. Toyota PHVs can supply enough energy on one tank of gas using its engine to power a standard home for around four days (40 kWh)

Manage power use from your smartphone

Users can manage home energy use in real-time using a smartphone. Regardless of location, users can check the PHV battery charge level, turn on or off heating and air-conditioning, and easily check a home's energy use. This information is empowering and can be used to plan a more efficient, greener way of living.

Low-carbon Project in Verification Phase

A project to verify the environmental benefits of an experimental home energy management system (HEMS) is underway in in Toyota City, Aichi Prefecture. This project seeks to reduce carbon dioxide emissions to create a low-carbon society. The HEMS will link energy generating and energy storage devices in the home with next-generation vehicles, such as PHVs and EVs, and intelligent household appliances to optimize and make visible power supply and demand as well as make possible the control of individual household devices.
At the local level, an energy data management system (EDMS) will coordinate electricity supply and demand in the area by linking structures including commercial facilities and schools, with the aim of creating and consuming energy within the community.

The smart mobility society considers the future of people, vehicles and communities

Toyota envisions a "smart mobility society" that contributes to a low carbon society and is working to achieve this goal in four key sectors.
Toyota links people, vehicles and communities through new technology and new concepts to create a motorized society that is vastly more eco-friendly and enjoyable.
Toyota is progressively making these dreams come true.

Toyota, together with several partners, is participating in a three-year verification project involving ultra-compact EV car sharing in the city of Grenoble, France.
Through this project, urban mobility will become much smoother and traffic congestion will be alleviated.

Due to future increases in population, new mobility systems will become necessary.

The diversification of mobility methods is a factor in easing traffic congestion, and this is seen as contributing to the realization of a low carbon society.
